Claims. (01. 55-13) A I a The present inventionrelates to new and useful improvements in agricultural implements particularly for scraping and harrowing ground which. has been planted in sugar cane but it will 5 be understood, ofcourse; that a machine in aceordancewwith-this invention may be used for any purpose for which it is found adapted and desirable.

An important object of the invention is to provide, in a manner as hereinafter set forth, an agricultural implement of the aforementioned characterzembodying a novel combination and arrangement" of ground engaging elements imountedufor rotation ina horizontal plane, together. with'novel means through the medium of which said elements may be convenientlyadjusted vertically as desired. 7 Another very. important object of the inven- .tion is to .providean agricultural implement of the character described comprising rotary scraperlelementsor units of 'a novel construetion. I 7

Still another important object of the invention is .to provide an agricultural implement of the character set'forth wherein stubble cutting disks may be-expeditiously. substituted for the rotary scrapers;

1 Other objects of theinvention areto provide an agricultural implement or machine of the character described which will be comparativelysimplein construction, strong, durable, high- 1ly efii'cient and reliable in use, compact, light in :weightand-which may be manufactured at low cost. I

All of the foregoing and still further objects 'and advantages of the invention will become apparent from a study-of the following specification, taken in. connection with the accompanying drawings wherein like characters of reference 49 .designate corresponding parts throughout the several views and wherein:-

. 1 Figure 1 Ba view in sideelevation of an agricultural implement constructed in accordance withthe present invention. I

Figure 2 is a view in top plan thereof. Figure 3, is a perspective viewof the frame.

Figure 4 is a detail view in plan of one of the cutting disks which may be used.

Figure 5 is a view in front elevation of a pair of the cutting disks.

Figure 6 is a detail view in bottom plan of the upper member of the hub portion of one of the rotary scrapers, showing two of the blades mount- 55 ed thereon.

Figure 7 is a view in vertical section through one of the rotary scrapers.

Referring now to the drawings in detail, it

will be seen that the embodiment of the invention which has been illustrated comprises a sub- 5 stantially' U-shaped frame which is designated generallyby the reference numeral I, said frame being of metal and including a top structure 2 mounted on legs 3 which rise from runners 4, said runners including upwardly curved forward 10 end portions 5 and further including upturned flanges 6 on their inner edges. Mounted longitudinally on the top structureZ of the frame I is a bar 1. On the forward end of the frame I suitable means 8 is provided for connection with 15 a suitable source of power. 7

Extending vertically between the forward portions of the runners' l and the top structure 2 of the frame I is apair of shafts S which are arranged diagonally with respect to each other. 20 The lower end portions of the shafts 9 are engaged in openings which are provided therefor in blocks II] which arefixed on the runners 4 and the upper end portions of said shafts extend through openings II which are provided there- 25 for in the top structure 2. Rotatably and slidably mounted on the'shafts 9 are scrapers which are designated generally by the reference numeral I2.

inner ends of said blades abutting the hub I3. 3.3

The lower face of the flange I9isprovided with radial grooves I6 for the reception of the blades l5. On the upper end portion of the hub I3 are spaced circumferential ribs or the like 20 providing a channel 2I.

Pivotally 'mounted on the bar I and rising therefrom is abracket 22 on the upper end of which a hand lever 23 is pivotally mounted at an intermediate point. Mounted on one end of the lever 23, through the medium of a link 24, is a horizontal bar 25. Yokes 26 depend from the end portions of the bar 25 and extend slidably through openings 21 which are provided therefor in the top structureZ of thefrarrie I. The yokes 26 straddle the vertical shafts 9 and so are rotatably connected at their lower ends to the scrapers I2 by means 28 engaged in the grooves or channels 2|. Suitable latching means 29 is provided for releasably securing the lever 23 in adjusted position. Braces l8 are connected
